that certain organic compounds emit light when exposed to radiation.With radiocarbon Radiocarbon dating is reliant on a carbon isotope, one of two or more atoms having the same atomic number but different atomic masses (1), known as carbon 14.There are three naturally occurring isotopes of carbon. Carbon 14 is extremely rare: one carbon 14 atom exists for every 1,000,000,000,000 carbon 12 atoms in living matter. When an organism dies there is no longer an uptake of C14 from the environment, only decay. The radioactive C14 atoms decay with a constant half-life Libby calculated at 5568 - 30 years.in the late 1940's by a team of scientists at the University of Chicago who were lead by Professor Willard F. For his work, Libby received the Nobel Prize in Chemistry in 1960.Today over one hundred thirty laboratories around the world date samples sent into them.
